Chickens do not care how much you spent on their nesting boxes.
Which is convenient, because apparently a 5-gallon bucket will do just fine.
The Happy Hen Nesting Bucket Kit turns almost any 5-gallon bucket into a simple, easy-to-clean chicken nesting box. Snap the perch onto the lid, snap the lid onto your bucket, mount the bucket securely, add nesting material, and you've got a perfectly respectable place for somebody to lay breakfast.
Want a little cushioning inside? Add a Happy Hen Nesting Pad to help cushion eggs and make nest cleanup easier.
For larger breeds, the entrance opening can be increased from 6" to 8".
That's it.
A bucket. A lid. A perch.
And somehow your chickens may like it better than the beautiful nesting box you spent actual money building for them.
Try not to take it personally.
